The Central Bank of the Argentine Republic (BCRA) issued Circular CAMEX 1-1057 to modify Communication A 3500, updating the data collection and calculation methodology for the Reference Exchange Rate (TCR) effective January 2, 2026. The revised framework mandates that the BCRA calculate the TCR daily as a weighted average of foreign transfer dollar against transfer pesos (UST$T) operations meeting specific criteria, including a minimum USD 500,000 amount, standard terms, and visible market bids. Furthermore, the updated provisions require daily publication of the TCR via Communication C, maintain USMEP operations on non-US business days, and ensure transaction data availability through the BCRA Library within three banking business days following processing.
